I downloaded one of your language translations, how do I install it?

To install another language you have to do two easy steps:

1. Download the desired language from the Translations page and extract it into "/language" folder.
You should have a folder whose name is the language locale code: en_us for American English, de_de for German, es_ar for Argentinian Spanish and so on, and a file called en_us.php or de_de.php, etc.

2. Open the "/config/config.php" file and set the value of the DEFAULT_LOCALIZATION option to the country code of the language you have unpacked in the "/language" folder (e.g. de_de for the German translation).
